SPECIFICATION forming peut of Letters Patent No. 360,184, dated March29, 1887.

Application filed June 13. 1886.

Serial No. 206,001. (No modul.)

Texas, have invented a new and Improved Motor for Ghurns, of which thefollowing is a full, clear, and exact description.

My invention relates to the construction of a cheap, durable, andefficient churn-power which may be placed in any convenient posivtionand used in connection with the ordinary form ofvertically-reciprocating dasherchurn.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the figures.

Figure 1 is a"front view of my improved form of churn-power, and Fig.2is aside view of the same, in partial section, parts being brokenawayto disclose the construction. Fig. 3 is a horizontal section takenon line x a" of Fig. 2.

In building such a churn-power as the one illustrated in the drawingsabove referred to, I provide a main frame, 10, that is preferably abouttwelve feet in height, and provided with a centrally-arranged toothedrack, 1l., and a grooved sheave or pulley, 12, said shcave or pulleybeing mounted above the upper crosspiece of the frame 10. A slidingframe, 13, provided with a platform, 14, is guided by ways formed in themain frame 10 by parallel strips 15, that are secured to the inner facesof the vertical posts of the said main frame, the vertical posts of thesliding frame 13 riding between said strips 15, a rope or chain, 16,extending upward from the frame and over the sheave 12, and aconnterbalancing-weight, 17, being suspended from the chain or rope 16.

A number of shafts, preferably four, as shown at 20, 21, 22, and 23, aremounted in proper bearings carried by the frame 13, the shaft 20 beingprovided with a pinion, 24, that is mounted upon said shaft, and heldfrom turning thereon by a feather; or the shaft may be squared and thesocket in the pinion correspondingly formed, this construction beingadopted in order that the pinion may be moved into and out of engagementwith the rack 11.

In addition to the pinion 24, the shaft 20 carries a large gear, 25,which gear is fixed to the shaft 20 and meshes with a pinion, 26,

carried by the shaft 2l, said shaft also carrying a fixed gear, 27,which meshes with apinion, 2S, that is carried by the shaft 22, upon theopposite end of which shaft 22 there is a large gear, 29, engaging with`a pinion, 30, on the shaft 23. The shaft 23, as shown, is mounted inforwardly-extending arms 3l, and upon one end carries a bevel-gear, 32,which meshes with a corresponding` bevel-gear, 33, carried by a verticalshaft, 3l, that is mounted iu proper bearings that arccarricd by theplatform 14 and one of the arms 31.

' Upon the shaft 34 there are arranged fans or' wings 35, that arecarried by a sleeve, 36, which sleeve is held to the shaft by asetscrew, 37. The shaft 23 is a crank-shaft, and to its crank 38 thereis connected a connecting-rod, 39,'which extends upward to engage withthe upwardly-extending arms 40 of a divided rock-shaft, 41; or, ifpreferred, the rockshaft 41 could be made in a single length and beprovided with a single forwardly-extending slotted arm. The arms 40 areprovided with a number of apertures, 2, and the shaft 41 is providedwith a rearwardly-extendiug lever, 43, which carries an adjustableweight, 44.

From the construction described it will be seen that if the frame 13 ismoved upward, and its pinion 24 brought into engagement with the rack 11of the stationary frame, in descending the crank-shaft 23 will berotated through the medium of the gearing intervening between the pinion24 and the said crankshaft, and it will also be secu that-as thecrankshaft is revolved motion will be imparted to the shaft 41.

In practice the dasher-shaft of a churn, 51, is secured between the arms40 of the shaft 41, the throw of the dasher being lengthened orshortened to suit the peculiar requirements of the case by connectingthe flasher-shaft to the arms 40 at varying distances from the shaft 41,it being of course understood th at this connection is made by a pinpassed through some particular pair of the apertures 2, and that thefarther the aperture is from the shaft 41 the greater will be the throwof the dasher. After the proper adjustment has been secured the frame 13is raised to the top of the frame 10, the pinion 24 being at this timedisconnected from the rack; but when the frame 13 has been moved to thetop of the frame 10 IOO the pinion 2l is brought into engagement with dthe rack 11,'aud the frame I8 is allowed to move slowly downward, theforce ofthe fall being controlled and governed by varying the Weight ofthe counter-balance 17. As the frame 13 descends the dasher will bevertically reciprocated and the cream or milk will be churned.

The fans 35 are designed to prevent the accumulation of ilies upon thetop of the churn, and should be adjusted so that in revolving they willcreate a current of air in a plane parallel with the said churn-top.

Although I have described a specific construction of gearing, it will ofcourse be understood that the number of shafts and wheels could bevaried, and that any other proper form ot' auxiliary gearing could beemployed instead of the form which I have specifically described.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is- 1 Thecombination, with a Inain frame provided With a rack, of a slidingframe, a counter-balance connected to the sliding frame by a rope orchain which passes over a sheave`
